Description

Single tube multi-cavity road formula esophagus conduction type intubating laryngeal mask airway

Technical field

This utility model relate to a kind of be applied to that surgery anesthesia, critical patient are rescued or other assisted respiartion set up the medical apparatus and instruments of artificial airway's ventilation, particularly a kind of single tube multi-cavity road formula esophagus conduction type intubating laryngeal mask airway for the patient.

Background technology

Intubating laryngeal mask airway is Brain in the nineteen eighty-three invention and at first advocates use a kind of and adopt the airway that mode is ventilated outside the glottis, it is easy and simple to handle, can substitute tracheal intubation rapidly for the patient sets up respiration channel, especially first-selected especially to the patient of a large amount of tracheal intubation difficulties.In order to improve the clinical application effect of intubating laryngeal mask airway, developed three types intubating laryngeal mask airway once: first kind is the standard type intubating laryngeal mask airway, it also is at present clinical intubating laryngeal mask airway the most commonly used, basic structure has cover capsule, airway and is the gas tube of cover capsule inflation, be mainly used in and keep the respiratory tract function, therefore but can not carry out drainage procedure to esophagus, for laryngemphraxis, full stomach, the patient of fasting water, acute abdomen, Abdomen Trauma, drug intoxication and digestive tract hemorrhage should not use; Second kind is the special-purpose intubating laryngeal mask airway of guidance tracheal intubation, and this kind intubating laryngeal mask airway is a kind of improved device that designs for guiding insertion tracheal intubation specially, and it is the endotracheal tube of 9.0mm that maximum can be drawn slotting internal diameter; The third is an esophagus conduction type intubating laryngeal mask airway, this kind intubating laryngeal mask airway can carry out drain to the esophageal reflux material, its basic structure is similar to the standard intubating laryngeal mask airway, just has a drainage tube parallel with breather, this drainage tube is by intubating laryngeal mask airway cover capsule and be opened on the tip of covering capsule, the tip can be blocked in patient's introitus oesophagi in use, thereby can attract esophageal reflux thing and gastric content by most advanced and sophisticated opening.But there is following defective in the intubating laryngeal mask airway of present this band drainage tube: (1) owing to be that multitube is set up in parallel, structure is complicated, and it is big to take up space, and has certain degree of difficulty during insertion; (2) the cover capsule easily produces displacement, influences sealing effectiveness; (3) only be provided with drainage tube and communicate, do not set up the passage between stomach and the atmosphere, both influenced the intragastric pressure balance, be unfavorable for drain, also easily cause the patient that diseases such as flatulence take place, reduced the safety coefficient of intubating laryngeal mask airway with esophagus.

The utility model content

Main purpose of the present utility model is to improve on existing esophagus conduction type intubating laryngeal mask airway basis at the problems referred to above, provide a kind of structure simple and direct, be easy to insert, set up the single tube multi-cavity road formula esophagus conduction type intubating laryngeal mask airway of esophagus and atmospheric connecting pipe and raising sealing effectiveness.

The technical scheme that its technical problem that solves this utility model adopts is:

A kind of single tube multi-cavity road formula esophagus conduction type intubating laryngeal mask airway, comprise cover capsule, breather, drainage tube and gas tube, it is characterized in that the integrated one-piece type body that is set to include ventilation tract, drain tract and inflation tract of described breather, drainage tube and gas tube; Body is fixedlyed connected with the cover capsule, the inflatable chamber connection that capsule is covered in venting cavity, the drainage lumens that is communicated with the human body esophagus and the connection of the mutual isolated connection person's windpipe of corresponding settings in described each tract and the cover capsule in the body.

Also be provided with connection esophagus and atmospheric connected chamber in described cover capsule, correspondence is provided with the connection tract in described body.

Described cover capsule is to be made of sealing gasket and connector; The side-glance shape of cover capsule is a duckbill, in duckbilled bottom part ring week the oval sealing gasket is set, sealing gasket top is connector, described drainage lumens, connected chamber, venting cavity and inflatable chamber are arranged in the connector, one end of drainage lumens and connected chamber correspondence respectively is connected to drain accent and the connection accent that the connector front end is offered, one end of venting cavity is connected to the ventilation accent that connector bottom corresponding sealing gasket central authorities offer, one end of inflatable chamber is connected to the inflation accent that connector upper ridge position is offered, the other end in aforementioned each chamber is connected to the body interface of being located at the connector rear end respectively, and is communicated with by interior each the corresponding tract of body interface and body; Cover the connector top and be provided with gas cell, gas cell is communicated with inflatable chamber by described inflation accent.

Described sealing gasket is real core cushion or middle mattress.

At the outside port of described body, described inflation tract is connected with an end of inflation connection tube, and the other end of inflation connection tube connects a pilot balloon, and Non-return air valve is installed on the pilot balloon; Described drain tract connects the drain connection tube; Described ventilation tract connects source of the gas.

The beneficial effects of the utility model are: (1) makes this intubating laryngeal mask airway structure simple and direct owing to adopt single tube multi-cavity road structure, and it is little to take up space, and is easier easily than traditional esophagus conduction type intubating laryngeal mask airway in inserting operation; (2) this intubating laryngeal mask airway can be with patient's esophagus communicates except that having drainage lumens, also being provided with connected chamber communicates with patient's esophagus, like this, make between patient's stomach and the atmosphere and set up passage, both can be when having discharged gastric juice and extra-nutrition the balance intragastric pressure, can prevent effectively also in the positive airway pressure that the gas that spills enters patient's gastric in gas cell, can prevent that the patient from flatulence taking place, improve the safety coefficient of intubating laryngeal mask airway, needing to be particularly useful for the patient of high pass air pressure.(3) top of cover capsule is provided with gas cell, and the bottom is provided with the structure of sealing gasket, and this intubating laryngeal mask airway can be subjected to displacement at inflation back cover capsule, and can form sealing effectively at human body larynx position; This utility model is particularly useful for the rescue of omnibearing anesthesia process and critical patient to be handled.
